DEVICE FOR TRANSMITTING MOTION.

SPECIFICATION forming part of Letters Patent-No. 420,678, dated February4, 1890. I Application filed April 16, 1889. Serial No. 307,444.. (Nomodel.)

.To all whom it may concern:

I Be it known that 1, JOHN WASHINGTON EISENHUTH, of San Francisco, inthe county of San Francisco and State of California, have invented a newand useful Improvement in Devices for Transmitting Motion, of which thefollowing is a full, clear, and exact description.

My invention relates to an improved device for transmitting motion,especially to that class of machines which are not attached permanentlyto a support-as, for instance, a clipping machine; and the invention hasfor its object to provide a portable device or crane automaticallyadjustable to the many positions that a movable machine undergoes whenfollowing various angles or assuming numerous different positions.

A further object of the invention is to provide a perfectly-balancedcrane of light and durable construction, and which may be convenientlyadjusted.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of a perpendicular crane. Fig.2 is acentral vertical section of the same, illustrating the intermediatesection in vertical alignment with the main section. Fig. 3 is atransverse section, partially on line 0c of Fig. 1. Fig. 4 is a sideelevation of the crane when attached to the ceiling. Fig. 5 is a centrallongitudinal section through the body of the device as illustrated inFig. 4, and Fig. 6 is a vertical section through the hanger and thebearings of the device when in the position illustrated in Figs. 4 and5.

In carrying out the invention, when the crane is to be placed. in aperpendicular position a base-plate 10 is provided, adapted forattachment to any suitable and convenient support, which plate isprovided with a central post 11, projecting upward therefrom, and anannular rib 12, surrounding the post a distance therefrom, as bestillustrated in Fig. 2.

The main frame of the crane consists of'a central standard provided atthe bottom with a recess adapted to receive the post 11 of the base,and. the lower end of the said main frame, which is circular, is of adiameter to loosely fit into the space intervening the said post 11 andthe annular rib 12.

Immediately above the base or lower end of the main frame a shelf orhorizontal platform 13 is made to project from opposite sides at a rightangle to the frame, the shelf upon one side being adapted to support themotor 14 employedfor instance, an electric motorin which event thebattery 15 is located upon the opposite side of the shelf, and the wiresconnecting the battery and the mo tor are passed through a suitableaperture in the frame. 4 Slightly above the base or lower end of themain frame the said frame is carried outward at each side to form alongitudinal loop or opening 16, and above the said loop 16 the frame isprovided with a longitudinalbore 17 and a set'screw 18, extending intothesaidbore. One end of an extension-rod 19 is inserted in the bore ofthe main frame, being held at any desired elevation by the saidset-screw 18. The upper extremity of the extension-rod 19 is forked, anda sheave or pulley 20 is journaled in said forked end, as bestillustrated in Fig. 2. A sleeve 21, forked at the inner end, is pivotedupon the corresponding forked end of the extension-rod 19 by the samebolt pivoting the sheave or pulley 20, whereby a swing-joint isprovided. From the forked extremity of the sleeve 21 arearwardly-extending balance-arm 22 is projected, and to the outerextremity of the said balance-arm 22 one end of a coil or spiral spring23 is secured, the other end of the said spring being attachedto a link24, pivoted in a lug 25 integral with the rear side of the main frame,as best illustrated .in Fig. 1.

Instead of the spring 23 and the link 24, a weight may be substituted,the said weight or spring being adapted to counterbalance the weight ofthe intermediate section of the device, of which the sleeve 21 is aportion.

In the sleeve 21 one extremity of the second extensiolrrod 25 isinserted, and the said rod is held within the sleeve in any desiredvertical position through the medium of a set-screw 26. The upperextremity of the second extension-rod 25 is forked, and in the saidforked end a cone-pulley 27 is pivoted. Near the swing-joint of thesleeve 21, with the first extension-rod 10, cars 28 are proj ected fromthe sleeve at a right angle in the direction of the front, as best shownin Fig. 1, between which cars a friction-pulley 29 is jou rn aled.

Through the loop or opening 16 of the main frame a shaft 30 ishorizontally projected,

having keyed thereto within the loop a cone pulley 31 of greaterdiameter than the upper cone-pulley 27. Upon one outer end of the saidshaft 30 a crank 32 is secured, and upon the opposite end or extremityoutside the loop 2 5 27 by a belt 36, which belt, upon the rear of themachine, passes over the sheave or pulley 20, which pulley prevents thebelt from coming in contact with the extension-rod 19 in its passageupward. At the front of the mao chine the belt passes upward over thefriction-pulley 29, as best illustrated in Fig. 1. Thus the belt is keptfrom contact with the lower extension-rod 19 upon all sides.

Near the forked extremity of the second ex- 3 5 tension-rod cars 37 areforwardly projected at a right angle to the rod, between which cars apulley 38 is journaled, and a guide-rod 39, provided with one forkedend, is also pivoted to the cars 37, the members of the fork 40 beingmade to engage with the outer surface of the ears. The smooth end of theguiderod 39, which rod constitutes a third extension-rod, is inserted ina sleeve 40, )rovided with a forked outer extremity, and a set screw 541 controls the movement of the guide-rod.

In the forked end of the sleeve 10 a grooved pulley 42 is journaled,which pulley is conneeted by a belt 43, which is preferably elastic,with the cone-pulley 27, as best illustrated in Fig. 1. The belts 35 and36 may also be elastic, if desired. When elastic belts are used, Iprefer to form them of solid or hollow rubber core and a fibrouscovering.

From the upper surface of the outer sleeve -10, at or near its innerend, a lug M is proj ected, to which lug a rope or chain is secured, thesaid rope or chain being made to pass over the pulley 3S, and hassecured at its free end a weight 40, sufficient to counterbalance theouter section of the frame and likewise the machine to which saidsection is attached. In practice it is desirable that the pulley 42 beattached to the machine to be driven, and the sleeve e0 may also beattached to the said machine, if in practice it is found advantageous.The main pulley 31 is made in the form of a cone, so as to provideonepulley for a crank when the motor is not employed and one for usewith a motor. The pulley used in connection with the motor is preferablysmaller than the one employed when the pulr ley is revolved by a crankIn Figs. 4, 5, and 6 I have illustrated the application of my device tothe ceiling of a building for the purpose of driving or communicatingmotion to a machine upon the door or at an elevation above the device.In

this latter construction an essentially U- shaped bracket 47 is securedto the wall or ceiling in any suitable or approved manner, and betweenthe members of the said bracket which constitute the lower end thereofthe main frame 458 of thcdevice is passed, the said frame consisting ofthe central body or loop-section 19, located between the said members ofthe hangers, an integral rearwardlyextending arm 50,andaforwardly-extending arm 51, provided with a forked outer end, asbest illustrated in Fi 4, in which forked outer end a cone-pulley 52 isjournaled.

The main frame 18 is pivoted in the hanger 47 by passing a shaft 53through the said hanger and through the loop-section of the frame, asbest illustrated in Figs. 5 and O, the members of the hanger beingprovided with suitable bearing-boxes to receive the shaft.

Upon the shaft 53,within the loop 49 of the main frame, a grooved pulley54; is rigidly so cured, and upon one outer end of the said shaft adrive-pulley 55 is rigidly attached adapted for connection with themotor or engine purposed to communicate power to the device.

The outer section of the hanging device illustrated in Figs. t and 5 ispreferably identical in construction with the outer section heretoforedescribed in the perpendicu lar form of the device illustrated in Figs.1 and 2.

Upon the rear arm 50 of the main frame 48 the weight 56 is adjustablysecured, which weight is adapted to counterbalance the for ward sectionof the main frame, the weight 46 of the outer section being adapted, asheretofore described, to counterbalance the weight of the outer sectionof the machine to which such section may be attached.

It is evident that the device illustrated in Figs. l and 5 is capable ofvertical movement, and if a rotary movement is also required the shankof the hanger 47 may be made in two sections provided with aswivelconnection.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combinatiomwith a support carrying a pulley, of a counterpoisedframe pivoted to the support and carrying a cone-pulley at its outerend, a telescopic and counterpoised outer section pivoted to the saidframe and carrying a pulleyat'its free end, and belts connecting theseveral pulleys, substantially as described.
